Important Bugfixes:
* Add missing callvalue check to the creation code of a contract that does not define a constructor but has a base that does define a constructor.
* Disallow index range accesses for arrays with dynamically encoded base types.
* Code Generator: Fixed that string literals containing backslash characters could cause incorrect code to be generated when passed directly to function calls or encoding functions when ABIEncoderV2 is active.
Language Features:

Compiler Features:
* Commandline Interface: Don't ignore `--yul-optimizations` in assembly mode.
* Allow using abi encoding functions for calldata array slices without explicit casts.
* Wasm binary output: Implement ``br`` and ``br_if``.

* Fixed an "Assembly Exception in Bytecode" error where requested functions were generated twice.
* Natspec: Fixed a bug that ignored ``@return`` tag when no other developer-documentation tags were present.
* Yul assembler: Fix source location of variable declarations without value.
* Type checker: Checks if a literal exponent in the ``**`` operation is too large or fractional.

The first line tells you that the source code is written for
Solidity version 0.4.0, or a newer version of the language up to, but not including version 0.7.0.
The first line tells you that the source code is licensed under the
GPL version 3.0. Machine-readable license specifiers are important
in a setting where publishing the source code is the default.
The next line specifies that the source code is written for
Solidity version 0.4.16, or a newer version of the language up to, but not including version 0.7.0.
This is to ensure that the contract is not compilable with a new (breaking) compiler version, where it could behave differently.
:ref:`Pragmas<pragma>` are common instructions for compilers about how to treat the
source code (e.g. `pragma once <https://en.wikipedia.org/wiki/Pragma_once>`_).

SPDX License Identifier
=======================
Trust in smart contract can be better established if their source code
is available. Since making source code available always touches on legal problems
with regards to copyright, the Solidity compiler encouranges the use
of machine-readable `SPDX license identifiers <https://spdx.org>`_.
Every source file should start with a comment indicating its license:
``// SPDX-License-Identifier: MIT``
The compiler does not validate that the license is part of the
`list allowed by SPDX <https://spdx.org/licenses/>`_, but
it does include the supplied string in the `bytecode metadata <metadata>`_.
If you do not want to specify a license or if the source code is
not open-source, please use the special value ``UNLICENSED``.
Supplying this comment of course does not free you from other
obligations related to licensing like having to mention
a specific license header in each source file or the
original copyright holder.
The comment is recognized by the compiler anywhere in the file at the
file level, but it is recommended to put it at the top of the file.
More information about how to use SPDX license identifiers
can be found at the `SPDX website <https://spdx.org/ids-how>`_.
